Soon after inheriting her family's stately home, eccentric artist Fenella Harford discovers a stash of hidden diaries and enlists a young academic, Marva, to confirm their authenticity. Joined by Marva’s brilliant but overlooked mentor, Abi, the three women come together to seek the truth, soon realising that secrets at the heart of Harford Hall were darker than they could have imagined.
